'llhis invention pertains to separable fasteners oit the slider operated type, example as described in the patent to Frentice, No. 1,658,392, February 7, 1928, and reto an improved actuating slider for such asteners. rlhe field ot usefulness of fasteners of this general class has been extended to include undergarments, lor example corsets, but tor such use the en- Ml tire fastener, including the actuating slider,

must be made ot assmall dimensions, particularly in a front to rear direction, as is practical, tor unless the fastener device be very flat and thin it may cause 5 outer garments, as well as real discomfort to the wearer. Usually the :fastener actuating slider is provided with a pull or operatin tab, commonly consisting o a piecel of meta adapted to be seized between the thumb and nger tor use'in moving the slider, and vordinarily this pull tab is attached toV the slider proper,` by means such as a rivet, lug, or loop, which projects out trom the plane ot the iront wing ot the slider, thus adding mi very materially to the bulkiness of the slider vin the iront to rear direction.,A

'.lhe principal object of the present invention is to avoid the above dimculty and to provide an acceptable slider tor the suggested purpose, which is of minimum front to rear thickness, although rovided with suitable operating means use ul in positively pulling the slider in either direction aloner the series of fastener elements.

M this invention l attain the desired object in to large scale of a a very simple way, and without necessitating substantial alteration in or departure from `'usual slider construction in so far as the slider body proper is concernedfand without adding substantially to the cost or complexity ot the processof manufacture.

lin the accompanying drawing wherein l have illustrated one speciiic embodiment of the invention by way of example,

Fig. 1 is a tra;Y entary iront elevation astener device of the type referred to, showing the actuating slider as spaced from one end of the .fastener and embodying the present invention;

Figs. 4 and 5 represent the shaping operation;

Fig. 6 is an edge elevation ot the slider complete, except for the pull members;

Fig. 7 is a section on the line (-7 `oit Fig. 6; and i Fig. 8 is a perspective view illustrating one ot the p ull attaching elements to large scale and detached from the slider proper.

Referring to the drawing, the numerals l. and 2 indicate flexible stringers ot the usual type employed in such fasteners, the respective stringers carrying the series of fastener further steps in elements 3 and l which may be ot any usual type. The opposed series 0i"l fastener elements are moved into and out et engaging relation by ineans of the slider 5 in a manner which is common and well known in the art.

Referring to Fig. 2, l prefer to make my improved slider from asingle piece or' sheet material which is cut, punched, or otherwise prepared, in `accordance with known processesf, the completed` blank comprising the front and rear wing portions t5 and 7, respectively, united by the neck portion 8., At the free end of one of the wings, for example the end ot the wing 6, l provide a pull attaching member consisting of a loo 9 preferably integral with the material o the wing and cooperating or eye 10. While as stated the loop member 9 is preferably formed integral with the is obvious that it might be made ot a separate ieee, soldered, welded, or otherwise secure in position.

After the preparation of the blank, the next step usually consists, as indicated in Fig. 3, in turning up the wings to form the ange members 1l and the lateral margins of with the latter to form an opening l titi 12, respectively. Following this danging portion transversely, as indicated at 13 lil@ ` shape,

f Fig. 4 Following this step, the neck ortion p 1s successively further depressed, w ile at the same time the transverse width of the slider is decreased by appropriately applied pressure, so that, as shown in Fig. 5, a dee trough-like recess 14 is formed at the nec portion of the slider extending from front to rear all as more fully described in the cogendingapplication of George`E. Prentice, erial No. 562,518, filed September 12, 1931. Preliminary to the next step in the operation, I prepare a second pull attachin member, such as shown for example in ig. 8. Such attaching member may, for example, be made by punching the desired shape from sheet material, although the exact mode of preparation of this part is immaterial, and in its preferred form is of substantially A comprising the upper or loop portion 15 and the transverse crossbar 17 which cooperate to define the opening or eye 16. Below the crossbar 17 the side members of this A-shape structure extend downwardly in the form of legs 18 and 19.

Having prepared the attaching member` as just described, the crossbar 17 of such attaching member is now placed in the recess 14 of the partially completed slider, and the corner j portions 20 and 21 of the latter are then;

caused to approach while continuing the lateral inward pressure upon the slider body, so that eventually the parts take the position indicated in Fig. 7 where the crossbar 17 is wholly conned or embedded within a recess or opening 14n extending from front to rearl throu h the tubular neck of the slider. During te operations of forming the slider body, substantially V-shaped recesses 22 are produced in the front and rear wings at the neck, and these recesses receive the downwardly projecting leg portions 18 and 19 of the second pull attaching member. These legs thus seated in the V-shaped recess substantially prevent the loop member 15 from swinging about the crossbar4 17 as an axis, so that the pull attaching member is rigidly held in position. At any suitable stage of the process the loop member 9 may, if desired, be deflected forwardly to a slight extent, as shown at 9'a in Fig. 6, to accommodate the thickness of the pull between the loo and the forward faces of the fastener e ements. For convenient actuation of the slider thus prepared, I preferably attach t0 the loop 15 a flexible ull member 23 consisting, for example o a piece of ribbon, tape, or the like, and likewise attach a similar pull member 24 to the loop member 9. These pull members 23 and 24 may be of a similar material and/or color to that of the garment to which the'fastener is to be applied, and being soft and iexible will not cause discomfort to the wearer. At the same time it may be noted that the pull attachin member 15 is disposed within the plane 0%' isame time, means is the body of the slider, as shown in Fig. 6, while the attaching member 9 may lie in such plane or very slightly deflected therefrom, as shown in Fig. 6. Thus, there is no substantial projection beyond the plane of the front wing, such -as unduly to increase the front and rear thickness of the slider, so that the fastenerJis well adapted for use on undergarments, where it does not occupy an undue amount of space and doesnot produce bulges in the outer garments or subject the wearer to discomfort or danger of injury. At the provided for positively pulling the slider in either direction along the series of fastener elements, so that the slider is adapted for use with fasteners which are not designed to be opened by a tearing apart action, or whenever it is desired to move the slider positively in opposite directions by means of directly applied force.

While I have disclosed a certain desirable embodiment of the invention, I wish it to be understood that the invention is not necessarily limited to this particular embodiment but that changes in shape, proportion and size of parts may be made as well as substitution of equivalentswithout departing from the spirit of the invention. Likewise it is to Ibe understood that while the invention has been shown in associationwith a slider made according to a certain described method,

the invention is vof broader utility and may be applied to sliders of other specific construction.

I claim:
